用两台服务器，搭建出一个双master双slave、无单点故障的高可用 RocketMQ 集群。此处假设两台服务器的物理 IP 分别为：192.168.50.1、192.168.50.2。
内容目录
1. 启动 NameServer 集群
2. 启动 Broker 集群
3. RocketMQ 可视化管理控制台：rocketmq-console
4. 集群测试
1. 启动 NameServer 集群
在两台服务器上分别启动 NameServer，可以得到一个无单点故障的 NameServer 服务，服务地址分别为：192.168.50.1:9876、192.168.50.2:9876。
2. 启动 Broker 集群
修改 Broker 配置文件，以使每台服务器上都可以启动一个 Master 角色 的 Broker 和 一个Slave 角色的 Broker。
首先找到 Broker 配置文件，此处我们搭建一个同步双写模式的集群，所以需要修改 2m-2s-sync 目录下的 broker 配置文件：
[root@157-89 ~]# cd /usr/local/rocketmq-all-4.3.2-bin-release/conf/ [root@157-89 conf]# ls 2m-2s-async 2m-2s-sync 2m-noslave broker.conf logback_broker.xml logback_namesrv.xml logback_tools.xml [root@157-89 conf]# cd 2m-2s-sync/ [root@157-89 2m-2s-sync]# ls broker-a.properties broker-a-s.properties broker-b.properties broker-b-s.properties
1） 修改 192.168.50.1 服务器上的 broker-a.properties 为 Master 角色的 Broker：
namesrvAddr=192.168.50.1:9876;192.168.50.2:9876 brokerClusterName=rocketMqCluster brokerIP1=192.168.50.1 brokerName=broker-a brokerId=0 deleteWhen=04 fileReservedTime=120 mapedFileSizeConsumeQueue=500000 brokerRole=SYNC_MASTER flushDiskType=ASYNC_FLUSH listenPort=10911 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/commitlog storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/consumequeue storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/index storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/checkpoint abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/abort
2) 修改 192.168.50.2 服务器上的 broker-b.properties 为 Master 角色的 Broker：
namesrvAddr=192.168.50.1:9876;192.168.50.2:9876 brokerClusterName=rocketMqCluster brokerIP1=192.168.50.2 brokerName=broker-b brokerId=0 deleteWhen=04 fileReservedTime=120 mapedFileSizeConsumeQueue=500000 brokerRole=SYNC_MASTER flushDiskType=ASYNC_FLUSH listenPort=10911 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/commitlog storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/consumequeue storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/index storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/checkpoint abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/abort
3) 修改 192.168.50.1 服务器上的 broker-b-s.properties 为 Slave 角色的 Broker：
namesrvAddr=192.168.50.1:9876;192.168.50.2:9876 brokerClusterName=rocketMqCluster brokerIP1=192.168.50.1 brokerName=broker-b brokerId=1 deleteWhen=04 fileReservedTime=120 mapedFileSizeConsumeQueue=500000 brokerRole=SLAVE flushDiskType=ASYNC_FLUSH listenPort=10921 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/commitlog storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/consumequeue storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/index storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/checkpoint abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/abort
4) 修改 192.168.50.2 服务器上的 broker-a-s.properties 为 Slave 角色的 Broker：
namesrvAddr=192.168.50.1:9876;192.168.50.2:9876 brokerClusterName=rocketMqCluster brokerIP1=192.168.50.2 brokerName=broker-a brokerId=1 deleteWhen=04 fileReservedTime=48 brokerRole=SLAVE flushDiskType=ASYNC_FLUSH listenPort=10921 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/commitlog storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/consumequeue storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/index storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/checkpoint abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/abort
一台服务器上启动多个Broker 时，需指定不同的端口号，记得防火墙放开 NameServer 和 Broker 中用到的端口号哦～
分别启动四个 Broker:
nohup sh bin/mqbroker -c broker_config_file &
3. RocketMQ 可视化管理控制台：rocketmq-console
在服务器 192.168.50.1 上安装即可，无需集群

4. 集群测试
Producer 测试代码：
public class SyncProducerTest { public static void main(String[] args) { DefaultMQProducer producer = new DefaultMQProducer("producer_test_group"); producer.setNamesrvAddr("39.107.153.215:9876;39.107.157.89:9876"); try{ producer.start(); for(int i=0;i<100;i++){ Message message = new Message("topic_test", "tag_test", ("Hello World" + 1).getBytes("UTF-8")); SendResult sendResult = producer.send(message); System.out.println(JSON.toJSON(sendResult)); } producer.shutdown(); }catch (Exception e){ e.printStackTrace(); } } }
Consumer 测试代码：
public class SyncConsumerTest { public static void main(String[] args) { DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("consumer_test_group"); consumer.setNamesrvAddr("39.107.153.215:9876;39.107.157.89:9876"); consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET); try { consumer.subscribe("topic_test", "*"); consumer.registerMessageListener((MessageListenerConcurrently) (messageList, context) -> { System.out.println(Thread.currentThread().getName() + " Receive New Message:" + messageList); return ConsumeConcurrentlyStatus.CONSUME_SUCCESS; }); consumer.start(); }catch (Exception e){ e.printStackTrace(); } } }
SyncProducerTest 运行日志：
SyncConsumerTest 运行日志：
通过日志可以看到，消费者、生产者收发消息都是正常的，我们去可视化管理控制台查看下 http://192.168.50.1:8080/rocketmq：
通过管控台可以看到，双 master 双 slave 的 broker 集群一切正常，并可进一步看到每个 broker 处理消息的情况。
